61 hose connectors and tee fittings in a pre-packaged assortment covering the barbed connector sizes used most in automotive vacuum, coolant, and emission hose routing. Straight connectors and tees in a range of hose ID sizes means the right fitting is in reach for vacuum line repairs, coolant bypass hose installations, and EVAP system service without sourcing individual fittings.

What's Included

Straight hose connectors — barbed, for joining two hoses end-to-end in the same diameter or as reducers
Tee fittings — barbed, for splitting a hose line into two branches
Multiple hose ID sizes covering common automotive vacuum and coolant hose diameters

Best For

General automotive service shops — vacuum and coolant hose connectors and tees are consumed during driveability, cooling system, and emissions repairs; having a range of sizes on hand prevents delays
Emissions and driveability specialists — EVAP and vacuum system repairs regularly require tee fitting replacements and hose junction repairs; this assortment covers the sizes most frequently encountered
Fleet maintenance operations — coolant bypass hose and vacuum system repairs on mixed vehicle fleets require a range of hose connector sizes that a single-size purchase can't cover

Common Hose Connector Applications

Hose barb connectors and tees are used throughout a vehicle's vacuum, cooling, and emissions systems:

Vacuum system — straight connectors join sections of vacuum line; tees split a vacuum source to two components (e.g., intake manifold to brake booster and EGR valve)
EVAP system — tee fittings connect vapor lines to purge valves and canister ports; replacement is common when plastic fittings crack with age
Cooling system bypass hoses — straight connectors are used on short heater hose and coolant bypass runs where a factory molded hose is no longer available
PCV and crankcase ventilation — tee fittings are common in PCV routing where the crankcase vent connects to both the intake and a separator

Always match the fitting barb diameter to the hose inside diameter, not the outside diameter. A barb that's too large for the hose will split it; too small will leak. Questions? Contact us.
